“Nidaros: The Portland Cement Cathedral” (Baker Memorial Lecture)

This week I attended the international conference “Rediscovering Traditional Mortars” in Trondheim. The conference was hosted by the Nidaros Cathedral Workshop and it was part of the annual conferences organised by the British Building Limes Forum and its Nordic counterpart.

I was lucky to be invited to keep two lectures, one on the experimental lime burning in Hyllestad earlier this year, and the Baker Memorial Lecture during the gala dinner. A very great honour to keep this traditional lecture for more than 230 delegates! I concentrated the lecture on the use of Portland Cement during the restoration of Nidaros Cathedral from 1869 on.

Experimental archaeology: Building a “classic”, intermittent limekiln and burning marble at Millstone Park, Hyllestad, Western Norway

It took us about six months: Building a cylindrical limekiln of the classic Roman/Medieval type with local materials only – stone rubble and clay. In June this year, we built the firing chamber and filled the kiln with 2.5 tons of local marble, covered the kiln with clay on a layer of spruce branches and started burning. Five days and five nights with much of the local community involved! Here’s an extended photo story of the project – the first of its kind in Norway. The quicklime (burnt marble) will be tested at Selja medieval monastery and other restoration projects in Norway. Thanks to all paid and volunteers and support from The ruin restoration programme of the Norwegian Directorate for Cultural Heritage, as well as Hyllestad Municipality! The project was carried out by The Norwegian Millstone Centre/The Museums in Sogn og Fjordane County. Continue reading
